1)对于.zip

linux下提供了zip和unzip程序，zip是压缩程序，unzip是解压程序。它们的参数选项很多，可用命令zip -help和unzip -help查看，这里只做简单介绍，举例说明一下其用法：

# zip yajiu.zip yajiu.jpg yajiu.png
这条命令是将yajiu.jpg和yajiu.png压缩成一个zip包
# zip yajiu.zip *.jpg
这条命令是将所有.jpg的文件压缩成一个zip包
# zip -r yajiu.zip yajiu
这条命令是将文件夹yajiu压缩成一个zip包
# unzip yajiu.zip
这条命令是将yajiu.zip中的所有文件解压出来

yajiu@yajiu-desktop:~$ cd 图片
yajiu@yajiu-desktop:~/图片zip yajiu.zip yajiu.jpg yajiu.png
updating: yajiu.jpg (deflated 34%)
updating: yajiu.png (deflated 0%)
yajiu@yajiu-desktop:~/图片$ zip yajiu.zip *.jpg
adding: 1.jpg (deflated 34%)
adding: 2.jpg (deflated 0%)
yajiu@yajiu-desktop:~/图片$ zip -r yajiu.zip yajiu
adding: yajiu/ (stored 0%)
adding: yajiu/yajiu.zip (stored 0%)
adding: yajiu/yajiu.jpg (deflated 34%)
adding: yajiu/yajiu.rar (deflated 0%)
adding: yajiu/yajiu.7z (deflated 0%)
adding: yajiu/yajiu.png (deflated 0%)
yajiu@yajiu-desktop:~/图片$ unzip yajiu.zip
Archive: yajiu.zip
replace 1.jpg? [y]es, [n]o, [A]ll, [N]one, [r]ename: y
inflating: 1.jpg
replace 2.jpg? [y]es, [n]o, [A]ll, [N]one, [r]ename: y

2)对于.rar

安装： sudo apt-get install rar unrar

或者可从http://www.rarsoft.com/download.htm下载 RAR for Linux 编译安装
# tar -xzpvf rarlinux-3.8.0.tar.gz
# cd rar
# make
这样就安装好了，安装之后就有了rar和unrar这两个程序，rar是压缩程序，unrar是解压程序。它们的参数选项很多，可用命令rar -help和unrar -help查看，这里亦简单举例说明一下其用法：

# rar a yajiu.rar yajiu.jpg yajiu.png
这条命令是将yajiu.jpg和yajiu.png压缩成一个rar包
# rar a yajiu.rar *.jpg
这条命令是将所有.jpg的文件压缩成一个rar包
# rar a yajiu.rar yajiu
这条命令是将文件夹yajiu压缩成一个rar包
# unrar e yajiu.rar
这条命令是将yajiu.rar中的所有文件解压出来

yajiu@yajiu-desktop:~$ cd 图片
yajiu@yajiu-desktop:~/图片$ rar a yajiu.rar yajiu.jpg yajiu.png
